Given numbers are 422,785,674,842

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 422,785,674,842 is 46999593790.

Find LCM of 422,785,674,842 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 211 x 785 x 337 x 421 = 46999593790

Therefore, the lowest common multiple of 422,785,674,842 is 46999593790.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

422 x 785 x 674 x 842 = 187998375160

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

422 : 1, 2, 211, 422

785 : 1, 5, 157, 785

674 : 1, 2, 337, 674

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,785,674,842, is 1.

Now, the common factors can be found like this.

422:2x 211

785:5x 157

674:2x 337

842:2x 421

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 187998375160/(1x4)

LCM = 187998375160/4

LCM = 46999593790

Thus, we can understand that the LCM of 422,785,674,842 is 46999593790.
